Open Campground has been under development since early 2007 and over that time it has gone through some changes. The constant in the system is that it has maintained backward compatibility and is developed in Ruby using Ruby on Rails with MySQL used as a database for the system information.
The live system demonstration will give you a good idea of how it works and what it does. I recommend you try that for a fuller understanding of the system.
From the first production release it has had a fairly stable set of features.
As the system matured a large number of new features and improvements to existing features were added. Following are a number of those changes.
Installation, features and use of the system are described in the User's Manual.
